Abstract:

In recent years, due to the development of distributed generation, the concept of a microgrid has been introduced. A microgrid is a small-scale grid that includes renewable energy sources such as wind turbines and solar energy, conventional energy sources such as microturbines, energy storage units such as batteries, and loads. The microgrid can operate connected to the utility or isolated from the utility. The microgrid can be grouped into AC and DC types. A hybrid microgrid is composed of an AC microgrid, a DC microgrid, and an interlinking converter between them. To optimally operate the linking converter, it should be properly controlled. In this paper, a method to control and manage the interlinking converter is proposed. In the proposed algorithm, the voltage and frequency at the terminal on the AC side, as well as the voltage at the terminal on the DC side, are measured to evaluate the load of both microgrids. Based on the proposed strategies, power transfer occurs between AC and DC microgrids in a manner that maximum efficiency is obtained. The proposed strategy is implemented in MATLAB/Simulink to demonstrate its effectiveness.
